DOGGING MEANS FOR SAFE OR VAULT DOOR AUTOMATICS.

SPECIFICATION forming part of Letters Patent No. 793,292, dated June 27, 1905.

Application filed October 7,1904. Serial No. 227,524.

To all whom it 'IJbf/[I/ concern:

Be it known that I, GUSTAV Gesswnm, a citizen of the United States, residingiu Plain tield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Dogging Means for Safe or Vault Door Automatics, of which the following is a specification.

The present invention is designed to pro vide improved means for dogging or locking the bolting or locking mechanism of a safe or vault door to prevent its Withdrawal by accident or otherwise except at the proper time and by the proper manipulation of the mechanism provided for that purpose, the primary object of the invention, however, being to provide a locking or dogging means which is effective, except at the proper time and by, the proper means, to prevent the operation of the automatic, should its tripper or tripping-latch be prematurely operated by accident or otherwise, and to accomplish this by a means which is simple in its construction and operation and which can be applied to timing and automatic mechanism as ordinarily constructed.

1n the present instance the improvement is constructed for application in connection with a bolting mechanism designed to prevent rotary movement of the door after it is rotated to its locked position, the bolts of which are operated by means of a spindle and gearing. This particular form of bolting mechanism, however, does not form a part of my invention, it being merely used to illustrate a mode of application of the present improvement.

This improvement may be used in connection with all forms of bolting or locking mechanism under the control of an automatic, 4 the primary object of the invention being, as stated, to dog or look the automatic against accidental or designed operation thereof other than by the proper means-that is to say, to prevent, on the accidental tripping ot' the automatic-controlling latch prior to the running down of the time-lock, the operation of the automatic, whatever be the form of the mechanism which may be used with and controlled by such automatic. \Vhen, however, a different form of mechanism is used than that 5 shown under the control of the automatic, the dogging or locking means herein shown would dog a part which would be connected with the automatic in such way as to lock the carriage or plunger thereof against retraction on the improper or premature operation of the tripping-latch and which part would not in such instance be a clutch-shifter.

The present improvement is shown applied to the timing and automatic mechani m illus- 6O trated in Patent No. (547,998, dated April 24, 1900, of which a detailed description thereof other than sufficient to illustrate the construction and operation of the present improvement is not deemed necessary. In that pat- 5 ented structure, however, which is one now frequently used in connection with safe or vaultdoors, particularly rotary doors in which means are used to prevent the rotation of the door after it is rotated to a locked position, 7 the automatic, which is connected with the boltwork ot' the door, whatever may be its form, is held against its retracting movement by means of a latch, (designated as 4,) which when the time-lock runs down is operated by what is termed an auxiliary tripping device 14, it not being in engagement with the latch 4 until the time-lock has completely run down, at which time it acts quickly to release the latch &, which in turn releases the several levers 3, thus permitting the automatic to retract the bolts with which it is connected. It will be noted, however, that the operation of this automatic to withdraw the bolts is thus only prevented by means of a 5 hook 16 at the end of the latch L, which hook in practice, in order to prevent accidental tripping, has been, together with the pin 16,

made with inclined faces, the intent being that the greater the pressure upon the hooked face of the latch A the tighter such pin, and thereby the automatic will be locked against movement; but experience has demonstrated that it may be possible to accidentally trip this latch 4, which is the only means, as stated, that holds the automatic against retraction, and consequently is the only means which prevents the unlocking of the safe-door if it be a bolted door and the only means of preventing rotation of the door if it be a rotary door. The present improvement therefore is designed to positively dog or deadlock the automatic should this latch or tripping device become accidentally tripped, either by concussion or otherwise, since, as will be obvious, if the part 6 is moved slightly, either by concussion or otherwise, in the same direction as the part 14 shifts it the tripping of the automatic would be completely effected and the door unlocked, since the proper locking of the door, either against rotation or against with drawal, as the case may be, according to the form of locking means used, depends upon the proper working of this latch 4, the inclined face of which latch, as stated, is depended upon to prevent such accidental tripping.

In the drawings accompanying and forming a part of this invention, Figure 1 is a view of the rear side of a door with the bolting mechanism, the means for operating it, and the timing and automatic mechanism hereinbefore referred to in its proper position in connection with this improved means for dogging such automatic, the view illustrating the bolts as retracted. Fig. 2 is a similar view to Fig. 1 on a somewhat smaller scale, but illustrating the bolts as protracted and the dogging mechanism in position to prevent the retraction of such bolts by the accidental tripping of the latch. Fig. 3 is a cross-sectional view taken in line a a, Fig. 2. Fig. 4 is a rear view illustrated as taken on line b b, Fig. 3, looking in the direction of the arrow; and Fig. 5 is a sectional view taken in line 0 c, Fig. 4, and looking toward the right hand.

Similar characters of referenceindicate corresponding parts in the different figures.

The door 30, which may be of any preferred form, is illustrated herein as a rotary integral door, of unmachineable metal, comprising a body 31 and a flange 32, having bolt-openings 33. Any suitable form of bolt mechanism for preventing the rotation of the door may be provided. In the present instance this bolt mechanism comprises a pair of right and left hand threaded oppositely-located bolts 34, the inner squared ends 35 ofwhich project into a sleeve 36, suitably supported. Loosely mounted upon this sleeve is a bevel-gear 37, meshing with a bevel-gear 38, fixedly secured to a tapered spindle 39, projecting through the body of the door and by means of which the bolts are shifted. The loosely-mounted bevel-gear is provided with clutch-teeth to mesh with clutch-teeth 41 of a clutch member 42, keyed to the said sleeve. For throwing the clutch members into and out of engagement a suitable clutch-shifter 43 is provided, pivoted to a plate 44, preferably secured to the body 31 of the door by means of screws or bolts 45 projecting into soft metal inserts 46, located in such door. In the present instance this clutch-shifter, which when shifted in one direction throws the splined clutch member into engagement with the clutch-teeth of the bevel-gear, and thus fixedly connects such gear with the sleeve, and thereby with the right and left hand threaded bolts, so that on the turning of the bevel-gear by means of the spindle the bolts will be retracted or protracted, and which when thrown in the opposite direction disengages the clutch members to prevent this manipulation of the bolts and is controlled in its operation by means of timing and automatic mechanism, which, as hereinbefore stated, may be in the usual form thereof. prises a suitable timing mechanism, (designated by A,) having the usual triple time movements, and a suitable automatic, (designated by 13,) properly connected, so that when the automatic is wound and the time mechanism properly set it will trip the automatic to throw the clutch-shifter 43 into position to engage the clutch members, so that the bolts can be manipulated by the spindle. This timing mechanism and automatic are shown supported by a plate 44, secured to an annular shoulder 44", formed on the door-flange. In view of the well-known construction of the timing and automatic mechanisms it is merely necessary to refer only to those parts thereof which have connection with the present improvement. The spring-controlled carriage or plunger 5 of the automatic is set by means of a hub 1 for the reception of the key or crank. This hub is provided with a hooked arm 2, cooperating with a system of levers 3 under the control of a latch or tripper 4 for locking such carriage in its set position. This latch 4 is shown projecting into the casing of the timing mechanism and is adapted to be tripped by means of an auxiliary tripping device 14, having a peripheral tooth to engage the end 6 of such latch and which latch should the auxiliary tripping device 14 fail to work This mechanism, as shown, com-- will be tripped, its end 6 being forced toward the left, Fig. 1, by means of the yoke 7, connected with the bar 12 by means of primary levers 8 and 9. The auxiliary device 14 is spring-actuated, being set by a plunger 26, and is locked in its set position by means of a detent 18, under the control of a releasingarm 23, carried by the primary lever 9 and which when the primary lever 9, which is fulcrumed upon the screw 20, is swung by the time movements releases the detent 18, whereupon the spring or springs of the auxiliary device moves the same to trip the latch 4, and should it fail to do so the yoke 7 which on the complete running down of the time movements is moved toward the left, Fig. 1, through the action of the bar 12, which is shifted toward the right, Fig. 1, by means of pins or studs carried by the dials of the time mechanism, which engage with projections on the rear of such bar 12, will accomplish this result.

The spring plunger or carriage 5 of the automatic is connected with the clutch-shifter 4:3, hereinbefore described, by means of a pin or stud H, which projects rearwardly of such member, such stud projecting into an elliptically-shaped opening48 of the clutch-shifter. From the foregoing it will be seen that when the automatic is set the carriage moving in the direction of the arrow a, Fig. 4;, will shift the clutch-shifter so as to carry the splined clutch member away from the teeth of the bevel-gear; but when the time movement runs down and the latch at is shifted to release the automatic and the spring-actuated carriage 5 moves in the direction of the arrow Z), Fig. 4, it will shift the clutch-shifter so that it will move the splined clutch member into engagement with the teeth of the bevel-gear and permit, through the medium of the companion bevel-gear and the spindle, the retraction of the bolts.

From the above it will be seen that in the present mechanism, as well as in any other form of mechanism known to me in which the automatic is under the control of a mere latch at, even though this latch may be itself held by a spring-controlled or yieldingly-supported guard, it is possible to trip this latch by concussion, especially as it is free and not engaged either by the yoke T or the auxiliary device 14 except when it is shifted, thus releasing the automatic, which of course would withdraw the bolts in the ordinary forms of bolting mechanism and in the present case shift the clutch-shifter so that by the manipulation of the spindle the bolts could be retracted. To prevent this, the present improvement is devised, which comprises a dogging means consisting of a hooked arm 50, the hub 51 of which is pivotally secured to the door, preferably by means of an insert 52, located in a suitable part of the door. A projecting part 53 of this arm is connected, by means of a link 54, with a part of the timelock mechanism. In the present instance it is connected thereto by means of a crank-pin 55, the arm 56 of which pin passes through an opening 57 in the bottom of the time-lock casing 58 and has its hub fixed to a stud 59, held in place by a screw 60 and upon which stud the hub of the primary arm 9 is located in such manner that the stud oscillates with the arm 9, so as to swing the dogging-arm 50 in a manner which will be readily understood. The assemblage of the parts is such that the crank-pin 55 fits relatively loosely in the end of the link 5%, and as the hub 51 of this link is supported between the plates 44 and 44 and as the clutch-shifter 43 is supported by the plate M, both of which supports are thus in front of the plate H, should the plate 44:, ordinarily termed the back plate, be blown off, together with the timing and automatic mechanism, the clutch-shifter would still be locked against movement, so that the bolts could not be retracted. It will thus be seen that although the time-locks control the locking device and operates it as it runs down such locking device would continue to lock the clutch-shifter against movement, even though both time-locks and automatic are blown into the interior of the safe, the pin or stud of the automatic slipping, of course, out of the opening in the clutch-shifter.

The hook of the dogginglcver in the present instance cooperates with a similarlyformed hook 61, carried by the clutch-shifter 43, although in those constructions in which a clutch-shifter would not be used its hooked part 61 could be formed on some other part or, in fact, be simply a hooked member having an opening for the reception of the pin of the spring-actuated plunger or carriage 5 of the automatic, so that should the latch 4t be shifted accidentally or prematurely the clutchshifter or other member provided for cooperation with the dogging-arm would be prevented from movement by such arm, as shown in Fig. 2, and thus the carriage or plunger of the automatic prevented from retracting the bolts. The action of the time movements, however, is such that the bar 12, and thereby the primary arms 9 and .10, are gradually shifted as the time movements run down, and during this final running down of the time movements the bar 12 moving toward the right in Fig. l throws the lower end of the primary arm 9 toward the left, thereby oscillating the locking-arm 50 and moving itaway from the clutch-shifter, so that as such time movements finally run down the primary arms 9 and 10 are further operated and release the detent 18, and thereby the auxiliary device lat, through the action of which the latch 4c is tripped, whereupon the retraction of the carriage 5 of the automatic moves the clutch shifter to throw the splined clutch member into engagement with the teeth of the bevel-gear, as hereinbefore set forth.

From the foregoing it will be seen that a safeguard is provided against the premature operation of the automatic on the accidental tripping of the latch L, so that the entire contents of a safe no longer depend upon the mere security of a swinging latch, as heretofore, which may be jarred by concussion to release the boltwork, but depend in addition upon a positively-acting locking mechanism that is, one .not merely held in position by means of a spring and which until the timelock has run down in its proper manner will not permit the operation of the automatic, and consequently will prevent the retraction of the bolts which may be used either to bolt the door to its seat or to prevent its rotation, as the case may be. Furthermore, it will also be observed that it is not the latch 4[ which is locked, but the plunger or carriage itself. In consequence should the tripper or latch be jarred it will not, as stated, release the plunger or carriage, as heretofore.

In the present organization while the automatic is locked against premature operation this is accomplished in a practical manner and by a means which is itself under the control of apart of the operating mechanism-to wit, the

time-lockso that it is positively set each time the locking mechanism is set and does not depend upon concussion or other violence to set it and is also properly released by a part of such mechanism, so that a lock-out does not result each time it is set, which would be the case if no means were provided to properly release this dogging means when the timelock runs down. Consequently each time the time-lock is set the dogging device is thrown into its effective position; but as this time lock runs down it is released to permit the bolts to be retracted.

In the mechanism shown it is necessary that some means be provided for holding the clutch members in engagement during a certain period to permit the bolts to be protracted after the door is rotated to its locked position, since the automatic must be set before the door is closed. In other words, as the automatic is set before the door is closed the protraction of the plunger would move the clutch-shifter, and thereby the splined clutch member with which it is connected, away from the clutchteeth of the bevel-gear, so that after the door is closed it would not be possible, owing to the fact that the clutch members would be then out of engagement, to rotate the bolts into their protracted position. For the purpose of holding the clutch-shifter against movement until the bolts are firmly shot home a suitable actuating device is provided comprising a spring-controlled arm 65, having a pin or stud to engage a collar 66 of one of the bolts. This arm is pivotally secured to the plate 44 and has its opposite end 67 hooked to engage a hooked portion 68 of the clutchshifter, so that when the bolts are in their retracted position the hooked portions of this lever and the clutch-shifter will engage, and consequently when the automatic is set the spring-actuated plunger will be prevented from moving, although the levers 3, which tend to hold it in such protracted position, will be set. As soon, however, as the bolts are fully protracted by means of the spindle and gearing the arm will be shifted so as to release the clutch-shifter, whereupon, owing to the fact that the plunger or carriage is under spring-pressure and the levers of which have been set, the clutch-shifter will be immediately shifted as the plunger moves into its proper position to carry the splined clutch member away from the teeth of the bevelgear, so that no longer can the bolts be manipulated by means of the spindle and which can only be done thereafter when the time movements have run down in the manner hereinbefore described. This part of the present subject-matter, however, is not a part of my invention except in so far as relates to the particular means for locking the automatic against accidental operation.

Theterm automatic as used herein is intended to mean a power devicesuch, for instance, as those now well known to and called by the trade an automatic and which comprises an organization of mechanism adapted to perform certain work when by means of a lock-such, for instance, as a time-lockits latch is tripped to release the spring-operated carriage or plunger of such automatic.

I am aware that it is not new to guard, by means of a yielding device, the latch or tripper of an automatic; but this guard depends for its efficiency upon a spring and is therefore not positively acting nor is it effective to prevent the automatic from operating should the tripper or latch be prematurely moved, which is possible, since the guard depends, as stated, upon the mere efficiency of the spring. a Moreover, in the structure referred to as the hookengaging surface of the latch and its cooperating part of the lever are not inclined the guard merely performs the Work which would be performed by the inclined surface of the hook and its cooperating lever were they inclined, and therefore is merely a substitute therefor and does not accomplish the object of the presentjinventionnamely, preventing the operation of the automatic should the latch itself be tripped prematurely.

Having thus described my invention, I claim- 1. In a safe or vault door bolting or locking mechanism, the combination with an automatic for controlling such bolting or locking mechanism, of means for dead-locking such automatic should the latch or tripper thereof be prematurely actuated, thereby to prevent the operation of the bolting or locking mechanism and means for releasing such dead-locking means at the proper time.
